Ultrasound exam to confirm the location and nature of the intestinal mass, regional lymph node involvement and guide tissue sampling if warranted.

Because there is a mechanical obstruction, surgical intervention is also required.

Most candidates identified the mass and focal loss of serosal detail, but several did not identify the abnormal segment of small intestine and its association with the mass. Some did not clearly conclude that this segment of intestine represented a mechanical obstruction or did not qualify the obstruction as chronic/partial. Differential diagnoses for the focal loss of detail often did not include mesenteric neoplastic infiltrate or possible rupture.
